DOOR HOLDER AND CHECK.

SPECIFICATION forming part'of Letters Patent No. 624,546, dated May 9, 1899.

Application filed September 16, 1897. $erial1lo. 651,945. (No model.)

To all whom, it may concern:

Be it known that I, FRANK L. RosENrRn- TER, acitizen of the United States, and a resident of the city of Rochester, in the county of Monroe and State of New York, have invented certain new and usefullmprovements in Door Holders and Checks, of which the following is a specification, reference being had to the accompanying drawings, in which Figure 1 is a side elevation of adevice embodying my invention, a portion being removed to exhibit construction. Fig. 2 is a top plan view of the catch mechanism and its support, a portion being removed to exhibit construction. Fig. 3 is a bottom plan view of the catch mechanism and its support. Fig.

4 is a longitudinal section on the lines 4 4 of- Figs. 2 and 3, showing the catch held in its non-retaining position. Fig. 5 is across-sec tion on the same line as Fig. 4, showing the hooked striker engaged by the catch mechanism and the latter held in its retaining position.

The object of my inventionis to produce a door-catch whereby a door may be held in an open position and from which the door may be released, the catch being certain in its retaining and non-retaining functions. The means of accomplishing these purposes are hereinafter set forth and claimed.

In the drawings, X is a bracket having one or more hooked strikers A for engagement with the catch mechanism hereinafter described. The bracket may be attached either to the door or to a wall. As indicated by the dotted lines in Fig. 1, the bracket, .if provided with a hooked striker at right angles to its vertical face, may be attached to the floor, and in order that the bracket may be adaptable to either of these situations I provide the same, as shown in said Fig; 1, with two strikers at right angles with each other, the hooked strikers proper being set upon terminal portions A of said bracket. The form of the striker is best shown in Fig. 5, wherein it is seen that it has two lateral projections a a, whereby the striker is reversible because it is double-hooked, so that the depending portion X of the bracket, as shown in Fig. 1, may extend either upward or downward, and therefore in either position a projection or hook of the striker is operative.

In Figs. 2 to 5, inclusive, is shown the catch mechanism, which consists in a support B, which is in reality a hollow casing having an opening B in the top thereof for the entrance and withdrawal of the striker A. \Vithin the casing and under one side of said opening is a tilting block or catch C, having the side pivotsC C, which rest in recesses formed by lugs 0 0 within the casing. The catch is thus adapted to tilt on its pivots. Transversely across the catch is a recess producing the arms 0 c in. the body of the catch. One side of the catch is flattened, as at 0 and at one end of the flattened portion is .a projection 0 upon the catch. The casing or support B at the other side of the opening B is provided with an abutment D, which forms a guide-surface to guide the hooked striker in its movement in and out of the support and which is set so far from the tilting catch C that when one side of the hooked striker is guided by the abutment D the other side or projection thereof must enter the recess in the tilting catch, and when the catch hastilted the striker remains in said recess and is engaged by the catch. A spring E is set in the support or casing B, and the tiltingcat'ch C constantly rests upon the spring. Thus when the flattened surface 0 rests upon the spring the catch is held in that position as shown in Fig. 5, and when the catch is tilted to a proper degree the projection c rests upon said spring and puts the springin tension, so that the catch is held in that tilted position, be-. cause, as shown in Fig. 4, the pressure of the spring is not toward the pivotal line of the catch, but at one side thereof, and in order that the catch should not be further turned by the tension of the spring the form of the casing or support B is such that one of the projections c strikes against the casing, and the catch, though pressed by the spring, cannot tilt farther.

If the catch is tiltedinto the position last described, the catch mechanism is in a nonretaining position with reference to the hooked striker, but is ready to receive the same, for if the striker is pushed through the opening B one edge, as a, comes against the abutment or guide D, while the opposite projection a rests upon a projection c of the catch in the recess thereof, and when the striker is moved farther inward the pressure upon said projection of the catch tilts the catch, so that the other projection comes over the projection a, of the striker, and when the flattened surface 0 is tilted so as to rest upon the spring E the hooked striker is held by the catch in a retaining position therefor. The catch is therefore adapted by means of the spring, the flattened surface 0 and the projection c to be held with reference to the hooked striker in a retaining position and a non-retaining position.

Of course I do not limit myself to the exact forms of the parts herein described, but I limit my claims only so far as the actual state of the art requires.

What I claim is 1. The combination of a striker having a projection from one side,a tilting catch adapted to be held in a retaining and a non-retaining position for engaging and releasing said striker, a spring mechanism for holding said catch in either of said positions, and an abutment for said striker adjacent to said catch.

2. The combination of a reversible doublehooked striker having the projections a and a, a tilting block 0 having a recess producing the arms 0 0 adapted to engage one of said' FRANK L. ROSENTRETER.
